Bugs In My Closet! Please Help!!!!!!?

in my walkin closet with a window, there are these little tiny brown bugs with a little red tail that move like a worm. They are mainly in one side of my closet and I found one crawling on my old halloween costume that was on my floor. The side where the bugs are contains of boxes, paper, bags and some clothing.... how do I make them go away? I don't know what they are and my parents CANNOT find out about them! What do I do? I did find some little holes on some of my old clothing!!!! Please help me! Best answer will receive 11 points!!!!!!
